I have played mostly to amuse myself and my family and friends for many years. Playing the guitar is a joy.
My advice is first to be honest with yourself about your interest and your expectations. Are you seriously interested in music, becoming a musician, joining a band, being the life of the party, playing and singing favorite songs or tunes, or 'picturing' yourself as a 'guitar player', or like me amusing and entertaining yourself and close friends and family. If you don't know it's ok. Get started and you'll sort it all out. You may find that it is just a 'flight of fancy' that fades if you don't get hooked right away.
But on to some other advice.
One of the greatest discouragements for beginners is the instrument they choose to learn on. You can start with an inexpensive guitar but it should be of good enough quality to sound good to your ear, be easy to play (finger), and be the right size for you. It should also be pleasing to look at.
The choice of which guitar depends on what kind of music you want to play. Electric for rock, acoustic for folk and traditional, classical for...classical. I'm guessing you will start with an acoustic, flat top, folk/country style guitar for which I have a recommendation: the Yamaha FG700S.

I have one and love it. It has the sound of a more expensive guitar, and it's low-but-buzz-free 'action' is the sweetest I have ever played. Hammer on's, slides, and pulloffs are clean and crisp. Cord changes are almost seamless as well as the guitar has great resonance. This is a great guitar even for intermediate players, which I consider myself to be.
It's a large guitar and a bit heavy, but this is no problem as you'll likely be sitting while playing. This guitar has great resonance, so much so that I place a small towel inside to dampen it down a bit. This is not a bad thing and is a technique many use to 'quiet' their guitars down if practicing into the night, as you will likely find yourself doing.
Regarding 'cut fingers'. You have to build callouses on your 'chording' hand, and you will have sore fingers to begin with. This can be mitigated by using a 'capo', which reduces the string height making chording easier on the fingers.
Tuning is easy using a 'tuner', but you should also learn to tune by ear.
I also suggest learning to strum chords before attempting 'picking'. This will get you familiar with the instrument and build those callouses. Good luck.
